Limitations & Future Work
While robust, the model requires further validation on underrepresented skin tones and could benefit from integrating 3D dermoscopic imaging. Future work includes pruning attention heads and exploring mixed-precision quantization.
Addressing Bias & Generalizability
The study acknowledges the need for further validation on underrepresented skin tones. Meta-learning methods are used to improve generalizability to different skin tones and imaging conditions, but ongoing efforts are crucial to ensure equitable performance across all demographics. This proactive approach to ethical AI development is vital for real-world deployment.
Future Enhancements & Scalability
Future improvements include integrating 3D dermoscopic imaging for depth analysis and systematically pruning redundant attention heads/GNN edges for efficiency. Exploring mixed-precision quantization (INT8 speed-ups) and knowledge distillation to derive streamlined student architectures will enhance deployment on constrained hardware, ensuring broad accessibility.
